canon rumors FORUM

If you have one of these lenses (or even any of the other Canon L long telephotos), I highly recommend the lens caps made by Don Zeck (http://www.donzecklenscap.com/) over the bulky "bag" lens caps that Canon provides with them. They are easy to install and remove, and will protect the front element in case you decide that you don't want to use the lens shade.I've been very happy with this lens, and I also find it very useful in shooting pictures of my grandson because I can get farther away from him so he's not as conscious of my taking his picture.1Ds Mk III, 1/640 @f3.2, ISO 250

*sigh* One of the lenses that I can only dream of holding one day, much less owning.

@eli72: Those look pretty nice, and quite reasonably priced as well. I bet you could make one using any of the home 3-D printers as well, although that's a lot more work. Cost a lot more if you don't already have the printer, for sure.
